JOURNAL- BEARING. I

SPECIFICATION forming part of Letters Patent No. 584,916, dated June 22,1897.

Application filed January 2, 1897.

7 and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements injournal-bearin gs, and especially to a roller-bearing for an axle-boxfor vehicle-shafts, &C.; and it consists in the provision of a circularseries of cylindrical rollers which are held within the box in rings,through which the spindles of the said rollers pass to support the same,suitable means being provided for lessening the amount of friction onthe spindles of the rollers, consisting of auxiliary disks which ride onthe circumference of the contracted ends of the rollers.

A further and important part of the invention consists in the provisionof two rings, each having a series of apertureswhich are adapted toregister with each other and through which the contracted ends of aseries of cylindrical rollers are adapted to pass, and a series ofantifriction-disks mounted between the said rings, eachantifriction-disk having a rolling contact with two of the spindles,whereby, as an axle turns on the rollers,

the friction on the latter is reduced to a minimum by reason of thespindles of the saidrollers turning on the antifriction-disks.

Another part of my invention relates to the provision of guide-wheels,which are placed at suitable locations on the stub-shafts about theouter ring, which wheels are adapted to travel in annular recesses inthe ends of the spindles of the rollers, thereby guiding the same andholding the rings in their proper position, between which rings theantifrictiondisks are journaled.

To these ends and to such others as the in- Vention may pertain the sameconsists, further, in the novel construction, combination, andadaptation of parts, as will be hereinaf- Serial No. 617,807. (Nomodel.)

lar letters of reference indicate like parts I throughout both Views, inwhich Figure l is a side View, partly in section, of a vehicle-hubequipped with my improved journal-bearings. Fig. 2 is an end elevationof the box, showing the manner of supportin g the rollers and also theauxiliary autifriction-disks bearing against the spindles of therollers, together with guide-wheels.

Reference now. being had to the details of the drawings by letter, Adesignates the box in the hub, and B represents the rollers, each ofwhich is provided with a contracted spindle end O, which is inclined atpoints 0, and near the end of each spindle is an annular recess D.

E is a ring having a series of apertures e, which are of sufficient sizeto admit of the free turning of the rollers or the inclined portion ofthe spindles of the rollers therein.

F is a second ring having a series of apertures f of sufficient size toallow a play to the spindles without touching the edges of suchapertures. Mounted between the two rings E and F on the shafts G is aseries of disks H, the circumferences of which are designed to havefrictional contact with the spindles of the rollers. In order to holdthe said disks from contacting against the rings on either side, it ismy purpose to employ washers on the shafts G. Located at certainintervals about the circumference of each of the said rings are thebraces K, which hold the said rings suitable distances apart. Mounted onthe stub-shafts L, which are carried by the outer roller-separatingrings at any suitable locations about the outer face of the outer ring,are the guide-wheels M, which are designed to travel in the annularrecesses D near the ends of the spindles 0, thus reducing to a minimumthe friction on the ends of the rollers, and the rollers will be keptapart and rings held securely in place.

To protect the ends of the rollers and to keep out dust and mud, asuitable cap B may be placed over the outer end of the hub and held inplace by means of screws or other suitable means, and which may beremoved when it is desired to take off the wheel.

Having thus described my invention, what 1 claim to be new, and desireto secure by Letters Patent, is

1. A roller-bearing for a journal-box, consisting of a circular seriesof rollers having contracted spindle ends, combined with two perforatedrings through which the ends of the said rollers pass, and theantifrictiondisks mounted between the said rings and designed to bearagainst said rollers, substantially as shown and described.

2. In a roller-bearing for journ al-boxes, the combination with therollers having tapering and contracted spindle ends, of the rings,perfora-ted to receive the spindle ends of the roll.-
